Louisiana Purchase (1803)

It sounds crazy today, but the Louisiana Purchase almost doubled the size of the United States overnight. Thomas Jefferson, at the time, the third to occupy the position of President of the United States, bought the massive 828,000 sq mi territory from France for $15 million, securing vital land and resources.

The purchase, however, didn’t mean that the United States also gained control of the totality of the territory, as it was inhabited by Native Americans. But in any case, the acquisition paved the way for westward expansion, providing a vast area for exploration and settlement, while enhancing America's geopolitical influence.

Commissioned by Jefferson, Meriwether Lewis and William Clark then embarked on a mission to map the newly acquired lands and find a viable route to the Pacific. Their legendary journey revealed the rich diversity of the western territories and established crucial relationships with Native American tribes.

Sacagawea, a Shoshone woman, played a crucial role as an interpreter and guide, helping the expedition navigate difficult terrain and gain trust with native tribes, significantly contributing to the mission's success. Ultimately, their detailed reports opened the frontier to future explorers and settlers.

The Oregon Trail (1811-1869)

Originally laid around 1811 by fur trappers and traders, the Oregon Trail soon became a critical route for thousands of emigrants moving west. Spanning over 2,000 miles from Missouri to Oregon, it was a perilous journey marked by harsh landscapes and, more often than not, disease.

Despite the hardships, the trail was improved to become passable by wagons, and it facilitated the mass migration of over 400,000 settlers during its peak, significantly contributing to the population growth and development of the Western United States.

California Gold Rush (1848-1855)

The discovery of gold at Sutter's Mill in 1848 triggered a massive influx of fortune seekers to California. The Gold Rush not only boosted the economy but also accelerated California's admission claim as the 31st state in 1850.

While prospectors initially used simple techniques like panning, the increasing complexity of gold extraction eventually required significant financing, favoring mining companies. And though the gold rush generated wealth worth tens of billions in today's dollars, only a few became rich; most participants earned little more than they had started with.

Homestead Act (1862)

Signed by President Abraham Lincoln, the Homestead Act offered 160 acres of public land to settlers willing to farm it for five years. The policy primarily encouraged individual farmers who were looking to operate their own farms, as opposed to slave owners who sought to buy large tracts of land and use slave labor.

The legislation encouraged widespread migration to the Great Plains, accelerating agricultural development and expanding American settlements across the West.

Building of the Transcontinental Railroad (1863-1869)

The completion of the first Transcontinental Railroad in 1869 revolutionized transportation in the United States. Connecting the East and West coasts, it facilitated trade, travel, and communication.

The extensive railroad network was built by three private companies on public lands, financed with federal bonds and various subsidies. Instrumental in the nation's economic growth, the Transcontinental Railroad also helped forge a sense of national unity and identity in the American consciousness.

The Great Sioux War (1876-1877)

Also known as the Black Hills War, the Great Sioux War was a series of conflicts between the United States and the Sioux tribes. The war was sparked by the encroachment of settlers and gold prospectors on Native lands, a conflict that had been escalating since the early 19th century.

Despite many Native American victories, such as the Battle of Little Bighorn - better known as Custer's Last Stand -, the war ultimately ended in the tribes' displacement. The conflict officially finished with the Agreement of 1877, in which the Sioux tribes were forced to cede property rights of their lands to the federal government, while clearly demarcated Indian reservations were established.

Oklahoma Land Rush (1889)

On April 22, 1889 - soon after the signing into law of the Indian Appropriations Act, which freed over two million acres of land for settlement - thousands of settlers raced to claim land in the Oklahoma Territory during the first of several land rushes.

Those who followed the rules and waited for the official start of the land rush were known as "boomers," while "sooners" sneaked into the territory before the designated time, risking penalties but gaining advantageous claims. This sparked hundreds of legal contests that had to be settled at local land offices or even by the U.S. Department of the Interior.

The Dawes Act (1887)

The Dawes Act aimed to assimilate Native Americans by dividing tribal lands into individual allotments. While intended to promote agriculture and integration, it resulted in the loss of tribal lands and culture.

The act was a controversial effort to reshape Native American society in the image of European-American settlers. It wasn’t until the Indian Reorganization Act, passed during the Franklin D. Roosevelt administration, that Native Americans regained some of their rights to own land collectively and form self-government.

Closing of the Frontier (1890)

In 1890, the U.S. Census Bureau declared the frontier closed, as there was no longer a discernible frontier line. This marked the end of a significant era of American expansion.

The closing of the frontier signified the nation's transition from a period of exploration and settlement to one of modernization and industrialization.

Origin of the name

Contrary to what you might think, the name "Hollywood" has nothing to do with the film industry. The origin of the name of the city that would later become the Mecca of cinema is surrounded by many myths. One comes from the personal diary of a real estate developer named H. J. Whitley. Whitley recounts encountering an Asian man carrying logs on a dolly. When asked about it, the man reportedly replied, "hauling wood," which, to Whitley, sounded something like "holly-wood."

As colorful as this story may be, it is unlikely to be true. The legend that likely comes closest to reality involves Harvey Henderson Wilcox and his wife, Daeida, who purchased 120 acres of land west of Los Angeles. According to different theories, Daeida may have overheard the word on a train or picked it up from the estate name of an acquaintance from Illinois. Whatever the case, since the name was first written on Wilcox's 1887 land deed, it seems plausible that Daeida was the one responsible for naming the area.

Movie theaters were prohibited

H. J. Whitley may not have christened the area, but he did a lot to promote its development. He invested heavily in installing electricity, built the Hollywood Hotel to attract land buyers, and developed the residential neighborhood of Whitley Heights. The area began to flourish, and by the early 20th century, the new municipality boasted a post office, a local newspaper, and two markets.

The inhabitants of Hollywood, by majority vote, decided to forbid the sale of liquor within the city, including in restaurants and hotels. Movie theaters were also banned . However, when Hollywood was incorporated into Los Angeles in 1910, which had no such restriction, history changed forever.

The motion picture industry conquers Hollywood

​​In the early 1900s, most film production companies were based in New York and New Jersey. However, the so-called "patent wars" encouraged them to move to the West Coast. At the time, the industry was virtually monopolized by Thomas Alva Edison, who owned the majority of the camera equipment patents.

Many companies rebelled against the abusive rates and decided to relocate to Los Angeles, where they could more easily evade these restrictions. In addition, the weather there was better and the days were longer, which allowed them to work more hours and spend less on electricity. If we add the low land prices to the mix, it’s no surprise that Hollywood became the ideal location to establish the capital of the motion picture industry.

The first film

The prolific film director D. W. Griffith, who had already made around 50 short films in New York, was one of the many who migrated to Hollywood to get rid of patent restrictions. In fact, he directed the first film shot entirely in Hollywood. In Old California is a 17-minute western set during California’s Mexican era.

Later, in 1915, Griffith would release The Birth of a Nation , one of the most important and controversial films in the history of the seventh art. This film, also shot in Hollywood, solidified Griffith’s reputation as one of the pioneers of narrative filmmaking .

The first studio

The first permanent motion picture studio established in Hollywood was the Nestor Motion Picture Company, a subsidiary of the Centaur Film Company from New Jersey. In 1911, brothers David and William Horsley built a rudimentary stage behind the Blondeau Tavern, at the intersection of Sunset Boulevard and Gower Street. Production started immediately, with films such as Her Indian Hero and The Law of the Range .

Despite their pioneering efforts, the Nestor Company faced the same fate as many other small studios of the era: its lifespan was short . In 1912 it was absorbed by the emerging Universal Studios, although it kept its name until 1917. In the 1930s, the original building was demolished to build the Columbia Square facility.

The truth about the Hollywood sign

The Hollywood Sign is a cultural icon not only of Los Angeles but of the entire United States. Do you know how it ended up on top of Mount Lee? In 1923, a publicist erected the famous 50-foot-tall white uppercase letters to promote a local real estate development called "Hollywoodland." The sign was originally intended to last only a year and a half, but the booming movie industry ensured its longevity.

With the great economic crisis of the 1930s, the company went bankrupt and the famous sign was neglected—even losing the "H," leaving it to read "Ollywoodland" for several years. In the late 1940s, the city decided to restore it, but the Chamber of Commerce ordered the last 4 letters to be removed so that it would no longer be associated with the company but with the town.

First Oscars ceremony

Everyone knows that the Oscars are the world's most prestigious film awards. But did you know that the ceremony has been held annually for almost 100 years? On May 16, 1929, as talkies were just beginning to rise in popularity, 270 film industry personalities gathered at the Roosevelt Hotel. That evening, 15 statuettes were awarded to give the booming film industry an air of prestige and glamour.

The inaugural night was filled with interesting curiosities. For instance, the recipients of the awards were announced publicly three months before the ceremony . Additionally, the event was not broadcast in any form of media. Another fun fact: In the early years, the Academy Awards included a banquet. However, in 1942, due to increased attendance and the impact of World War II, the banquets were replaced with more modest theater ceremonies.

Walk of fame

Every high-profile artist has a star on the Hollywood Walk of Fame—even the Muppets have one! Along 15 blocks in Hollywood Boulevard, approximately 2,800 five-pointed terrazzo-and-brass stars honor some of the world’s most beloved celebrities, including actors, directors, musicians, athletes, and even fictional characters.

In 1953, the head of the Hollywood Chamber of Commerce came up with the idea of creating a publicity stunt to promote those whose names stand for glamour and prestige. Finally, in 1960, the first star prototypes were installed, honoring icons such as Joanne Woodward and Burt Lancaster. Today, this popular landmark is visited by millions of tourists every year.

Time capsule

Few people know that beneath the mythical stars lies a very special treasure. To commemorate the Hollywood Walk of Fame's half-century of existence, the Chamber of Commerce buried a time capsule beneath the spot where it originated, at the corner of Hollywood Blvd. and Highland.

The 16 x 16 x 18-inch capsule holds an array of artifacts that celebrate Hollywood’s enduring mystique. Among its contents are the screenplay of Casablanca , recordings of Oscar ceremonies from 1960 to 2010, programs from the musicals Wicked and The Lion King , and messages from various Academy members. These priceless mementos are set to resurface during the Walk of Fame's 100th anniversary celebration in 2060.

The Hollywood Forever Cemetery

With its legendary sign, iconic Walk of Fame, and countless beloved films and celebrities, Hollywood truly has it all. For this reason, it is only fitting that the city also boasts a peaceful and beautiful resting place for stars after their deaths. Founded in 1899, the Hollywood Forever Cemetery is the final resting place of many stars, including Judy Garland, Cecil B. DeMille, Don Adams, and Peter Lorre.

Located in the heart of Hollywood and adjacent to Paramount Studios, today this cemetery is a tourist attraction visited by many. In fact, on weekends during the summer the cemetery screens outdoor films for everyone to enjoy!

Beehives

The first entry on the list goes to perhaps the most famous and finest example of animal architecture: the beehive. Built by incredibly industrious insects, beehives are among the most efficient structures in nature .

The regular hexagons provide the least-perimeter way to enclose infinitely many unit areas in the plane: the best way to separate the surface of their hives in equal parts all around, using the least possible total perimeter, thus reaching 100% efficiency in design.

Ant colony

If beehives aren’t the first thing that comes to mind when thinking about animal architecture, there’s a good chance you’re thinking of ant colonies.

Ants build the elaborate colony structure by hollowing out the area with their mandibles, grain by grain, without a blueprint, without a leader, and in total darkness . Unless the soil dries out dramatically, the chambers will keep their form.

Prairie dog town

These cute creatures excavate their homes by digging burrows into the ground, primarily in the Great Plains of North America. The region experiences extreme seasonal weather variations from season to season, requiring their homes to be built to withstand extreme temperatures, floods, and fires.

These underground "towns" have nursery rooms, pantries, living quarters, and temporary refuges —each smartly separated to serve a specific purpose.

Beaver dam

Another famous animal architect, the beaver, uses felled trees to build dams . These dams create still ponds where beavers can construct their winter homes, called lodges.

These creatures prepare for winter by covering their lodge with a fresh coat of mud, which hardens to create a barrier against the cold and predators.

It’s no secret that octopuses are incredibly intelligent animals, and their dens are proof of it. These clever mollusks use shells, stones, and even discarded human objects to reinforce their homes . Some species go a step further, decorating their dens with seaweed and other found materials.

7

Bagworm silk tent

Bagworms construct silk tents around themselves using bits of leaves, twigs, and other debris . These tents serve as mobile homes, providing protection as the insect feeds and grows.

Some species even camouflage their bags to blend into the environment, helping them avoid predators.

Coral reefs are massive structures built by tiny coral polyps. These marine architects secrete calcium carbonate to form hard skeletons, gradually creating vast and complex habitats for a myriad of marine species. They are often referred to as the "rainforests of the sea" due to their biodiversity.

10

Spider web

Another famous architect from the animal kingdom, the spider, creates webs that serve as both homes and hunting tools . The silk used in these webs is incredibly strong, and different species produce a variety of designs, including sheets, orbs, and funnel shapes.

11

Swallow nest

Swallows build cup-shaped nests that can house entire colonies , using mud pellets, usually attached to vertical surfaces like cliffs or man-made structures.

The construction is precise and stable, providing protection for their young against predators and environmental elements.

As their name suggests, burrowing owls make their homes underground , often taking over burrows abandoned by prairie dogs or other mammals.

They use these subterranean homes to protect their young and hide from the heat of the day.
