Tacoma is a mid-sized urban port city in and the county seat of Pierce County,Washington, United States.The population was 198,397, according to the 2010 census.
The city of Tacoma and surrounding areas were inhabited for thousands of years by American Indians, predominantly the Puyallup people, who lived in settlements on the delta.Tacoma was incorporated on November 12, 1875, following the merger of Old Tacoma and New Tacoma on January 7, 1884. Its hopes to be the "City of Destiny" were stimulated by selection in 1873 as the western terminus of the Northern Pacific Railroad, thanks to lobbying by McCarver, future mayor John Wilson Sprague, and others. The transcontinental link was effected in 1887, but the railroad built its depot on "New Tacoma", two miles (3 km) south of the Carr-McCarver development. The two communities grew together and joined.
