Between the first “land run” opening up the “Unassigned Lands” of Indian Territory in 1889 and statehood in 1907, Oklahoma filled up rapidly.
There were a variety of reasons, of course. The “frontier” was rapidly closing and Oklahoma Territory was the last hope of true homesteading on the continent. Early reports suggested fertile soil and cooperative climate – descriptions which would later be recalled in wry reflection by those who'd embraced them. Then there was the sheer newness and unpredictability of it all – in a nation built on restlessness and possibilities, that alone was sometimes enough.
Oh – and of course, it was a great place to get a divorce.
