Line 1:

Rio Rico was a city in Texas near the [[Rio Grande River]]. In 1906, an irrigation company performed an unauthorized diversion of the Rio Grande, which moved Rio Rico south of the river. Mexican authorities eventually assumed control of the area. However, since the course change was due to man made changes and not natural changes, International Law dictated that the land remained U.S. territory. The U.S. eventually ceded the territory to Mexico with [[Boundary Treaty of 1970]]. The handover took place in 1972. Anyone born in the city before the 1972 handover was able to retain U.S. citizenship.

This was the last time land from the 50 US states was ceded to a foreign country.
