The first Orioles were teams in the 19th Century.
Then a team had the name for the first three years of the American League (1901-1903). They moved to New York and became the Highlanders, and later achieved some notoriety under the name “Yankees”. You might have heard of them.
The were two more minor leagues teams in the International League from 1903-1914 and from 1916 to 1953.
The St Louis Browns moved to Baltimore and became the current incarnation of the Orioles in 1954.
Thanks for the information. I was familiar with the evolution of some of the old teams - Dodgers, Giants, Athletics - but not the O’s.
