Washington Territory was created in 1853, then it became the 42nd state in 1889. Washington, D.C. had been the capitol since
1800.
Surely someone must have realized the confusion that would ensue, not to mention the fact that it displayed a lack of creativity
on the part of whoever named it.
Basically, in 1852, the Northern residents of what was the large Oregon Territory, decided to petition to become their own territory, suggesting they be the Columbia Territory. When the bill came out of the House/Senate, someone changed the name to honor George Washington. They called it Washington Territory to prevent confusion with DC.
And irony. Congress is big on irony. Otherwise they’d have to wear wrinkled clothes…
It should be noted that at that time, Washington DC was not a very big town. And it wasn’t obvious that it would become a large city. In those pre-Civil War days, the federal government was very small and there was no indication that that would ever change.
Washington State was almost named by the Russians. Or was it the Spainards? The Chinook Indians were on the Columbia Slough when Lewis & Clark arrived. But there was a settled, domestic, unfriendly military fort on the mouth of the Columbia overlooking the Pacific.
According to the Geographic Names Information System, there are 147 populated places named Washington or having Washington as part of its name. There are also 31 States having a county so named.
There was a lot of “Washington” naming in the 19th century. My home twon in N.J. was called “Washington”, but they changed it because there were two other towns named “Washington” in NJ, and it was confusing the postal service.
