Baltimore was named to honor the title of Maryland's founding family, the six Lords Baltimore. It was a tiny village of 200 homes in 1768 when it became the Baltimore County seat. The city was separated from Baltimore County and given status equal to that of the counties in 1851. Baltimore is the 13th largest and one of only two independent cities in the United States. With a world port, government offices, significant medical and educational institutions, and major tourist attractions, Baltimore is one of the most important cities on the East Coast.
