πŸ‡ΊπŸ‡Έ United States historical map

This map attempts to show all border changes for US States from 1790 to today.

  • The changing boundaries are represented with a "lifetime" for each State, i.e. a start and end year.
  • To make sure that each states's changing borders are shown only once, the state of the borders at the end of each year (31/12/XXXX) is used.
  • For example, Oklahoma State was admitted on November 16, 1907 and consequently was already a state at the end of 1907, so the previous entities (Indian Territory and Oklahoma Territory) have an end date of 1906.
  • The map currently changes with a leap of 10 years, but more dates will be available in time.
  • Check the accompanying blog post for more info.
