Dallas, Texas was established in 1841 and became a city on February 2, 1856. Over 300 years ago the first Europeans came to the Texas area. Soon groups of people from Mexico, Europe and the United States followed. Mexico became free from Spain in 1821, and the location known as Texas became part of the United States of Mexico. Texas broke from Mexico in 1836 and joined the United States of America in 1846 after being independent for 10 years. During the Civil War Texas joined the Confederacy, however, except for that brief time, Texas has been a state for more than 150 years.
The city of Dallas's economy is mostly based on the oil industry, telecommunications, computer technology, banking, and transportation. It is the center of the biggest inland metro area in the U.S. and does not have any water link to the sea. Dallas's importance in spite of not being a harbor comes from its historical prominance as a center for the oil and cotton business.
Dallas is the third largest city in the state of Texas and the ninth largest in the United States. The city covers 385 square miles (997 km²) and has a population of over 1.2 million people. Dallas is the main economic center of the 12-county Dallasâ€“Fort Worth metro area, at over 6.1 million people, it is the fourth largest metropolitan area in the U.S. Dallas is today the third best location for business travel, and the Dallas Convention Center is one of the busiest in the country.
Some attractions are The Dallas Museum of Art, Dallas World Aquarium & Zoological Gardens, Mount Bonnel, Dallas Arboretum & Botanical Gardens and Dallas Zoo.
Dallas has a humid subtropical climate, yet this part of Texas also tends to receive warm, dry winds from the north and west in the summer. Winters are generally mild with daytime highs between 50 °F (10 °C) and 65 °F (18 °C) and nighttime lows between 30 °F (-1 °C) and 50 °F (10 °C). Cold fronts can go through Dallas, taking nightly lows below 30 °F (-1 °C). Snowfall is very minimal and there are times when warm and humid air from the south overcomes the cold, dry air, and freezing rain can occur. Sometimes daytime highs can go above 65 °F (18 °C) during the winter season. So, extremes in weather happen more in Dallas and Texas as a whole rather than along the U.S. coastlines, because Texas is in the center of the U.S.
Spring and autumn are very mild. Colorful wildflowers bloom in spring and grow around the roadways all over Texas. Springtime can bring storms, but temperatures are mostly moderate. Dallas is pleasant between late September and early November, and violent storms seldom happen in the area.
