Historical Background
Nevada’s history is deeply intertwined with its mining heritage and its strategic location in the western United States. Originally inhabited by Native American tribes such as the Shoshone, Paiute, and Washoe, the region saw the arrival of European explorers in the early 19th century.
In the mid-1800s, the discovery of silver and other minerals in Nevada spurred a rush of settlers and miners. The Comstock Lode, discovered in 1859, was one of the largest and most valuable silver deposits in the world, and it played a crucial role in Nevada’s development.
Nevada was admitted as the 36th state of the United States on October 31, 1864, during the Civil War. Its statehood was expedited by the federal government due to its strategic location and the importance of its mineral resources. The state’s admission was also seen as a way to support the Union war effort with additional resources and support.

These tribes developed rich cultural traditions and intricate systems of agriculture, art, and social organization.
Spanish explorers were the first Europeans to enter Arizona in the 16th century, but it was not until the late 17th century that Spanish missions and settlements began to establish a more permanent presence. Arizona became part of Mexico following its independence from Spain in 1821.
The Gadsden Purchase of 1853, in which the United States bought land from Mexico to facilitate the construction of a southern transcontinental railroad, added much of what is now southern Arizona to the U.S. In 1863, during the American Civil War, Arizona was established as a separate territory, distinct from New Mexico.
Arizona became the 48th state of the United States on February 14, 1912. The state’s development was driven by the mining industry, particularly copper mining, which remains a significant economic driver. Over time, Arizona has also become known for its tourism, agriculture, and its growing technological sector.
Today, Arizona is recognized for its stunning natural landscapes, including deserts, canyons, and mountain ranges, as well as its vibrant cultural heritage that blends Native American, Hispanic, and Anglo influences.

California is home to both the highest and lowest points in the contiguous United States. Mount Whitney, the highest peak, stands at 14,505 feet (4,421 meters), while Badwater Basin in Death Valley is 282 feet (86 meters) below sea level.
Historical Background
California has a dynamic history shaped by indigenous cultures, European exploration, and rapid growth following its incorporation into the United States. Long before European contact, California was home to numerous Native American tribes, each with its own distinct culture and way of life.
The first European to explore the California coast was the Portuguese explorer Juan Rodríguez Cabrillo in 1542, who sailed under the Spanish flag. Over the next two centuries, Spanish missionaries and settlers established a series of missions, presidios, and pueblos across the region, laying the foundations for modern California.
California became part of Mexico when it gained independence from Spain in 1821. However, the region’s history took a dramatic turn in 1848 when the Treaty of Guadalupe Hidalgo ended the Mexican-American War, and California was ceded to the United States.
The discovery of gold at Sutter’s Mill in 1848 triggered the famous California Gold Rush, attracting hundreds of thousands of settlers from across the world. This rapid influx of people led to California being fast-tracked to statehood, and it was admitted as the 31st state on September 9, 1850.
Today, California is known for its diverse economy, which includes technology, entertainment, agriculture, and tourism. It is the most populous state in the U.S. and has a significant cultural and economic influence both nationally and globally.
2. Texas
Total Area: 268,596 sq mi (695,662 km²)
Land Area: 261,232 sq mi (676,587 km²)
Water Area: 7,365 sq mi (19,075 km²)
Percentage of Water: 2.7%
Texas, the second-largest state in the United States, covers a total area of 268,596 square miles (695,662 km²). Of this, 261,232 square miles (676,587 km²) is land, and 7,365 square miles (19,075 km²) is water, accounting for 2.7% of the state’s total area.
Texas is the only state to have been an independent nation before joining the United States. The Republic of Texas existed from 1836 to 1845, when the U.S. annexed it as the 28th state.
Historical Background
Texas has a rich and storied history, marked by its transition from a Spanish territory to an independent republic, and finally, to a U.S. state. Originally inhabited by various indigenous peoples, Texas was claimed by Spain in the 16th century and later became part of Mexico following its independence from Spain in 1821.
During the early 19th century, American settlers began moving into Texas, which eventually led to tensions with the Mexican government. These tensions culminated in the Texas Revolution (1835–1836), during which Texas fought for and won its independence from Mexico. On March 2, 1836, Texas declared itself an independent republic, and after a decisive victory at the Battle of San Jacinto, it secured its independence.
The Republic of Texas existed as an independent nation for nearly a decade before it was annexed by the United States on December 29, 1845, becoming the 28th state. This annexation played a significant role in the lead-up to the Mexican-American War (1846–1848).
Texas’s vast size, diverse landscapes, and abundant natural resources, including oil, have made it one of the most economically powerful states in the U.S. Its history of independence and cultural distinctiveness continues to influence its identity today.
1. Alaska
Total Area: 665,384 sq mi (1,723,337 km²)
Land Area: 570,641 sq mi (1,477,953 km²)
Water Area: 94,743 sq mi (245,383 km²)
Percentage of Water: 14.2%
Alaska, the largest state in the United States, has a total area of 665,384 square miles (1,723,337 km²). Of this vast expanse, 570,641 square miles (1,477,953 km²) is land, and 94,743 square miles (245,383 km²) is water, making up 14.2% of the state’s total area.
Alaska’s immense size is more than twice that of Texas, the second-largest state, and it accounts for about one-sixth of the entire land area of the United States. Alaska is so large that it could fit the 22 smallest U.S. states within its borders and still have room left over. Despite its size, it has the lowest population density of any state, with vast areas of untouched wilderness.
Historical Background
Alaska has a unique and fascinating history, particularly in its relationship with the United States. Originally inhabited by various indigenous groups for thousands of years, Russia claimed Alaska in the 18th century.
In 1867, the United States purchased Alaska from Russia for $7.2 million, a transaction often referred to as “Seward’s Folly” after then-Secretary of State William H. Seward, who negotiated the deal. At the time, many Americans viewed the purchase as a waste of money, believing Alaska to be a barren, frozen wasteland. However, the discovery of gold in the late 19th century and later oil reserves in the 20th century proved the acquisition to be incredibly valuable.
Alaska became the 49th state of the United States on January 3, 1959. Its strategic location and vast natural resources have since made it a significant part of the nation’s economy and defense infrastructure.
