When the people of Texas overthrew the Santa Anna's shackles of centralist tyranny and established the Republic of Texas, General Sam Houston served as the second President of the Republic.
President Houston's government was located in the sixth and penultimate capital of the Republic--the nascent City of Houston. Pictured above is the Presidential Residence in 1837, a year after independence.
The Texas historical X account Traces of Texas informs us that the famous naturalist John J. Audubon visited President Houston and his cabinet in this home. It was a rough but serviceable home. A current Google Street View of the location at 405 Main Street reveals significant construction since 1837.
