In 1852, the city of Alexandria was separated from the rest of the county and has been a county since then. This gave rise to recurring confusion between the rest of County Alexandria and Alexandria City. For this reason, the former county was renamed Arlington County in 1920 , after the Arlington House , which is located on the also named Arlington Cemetery .
