It was named for George Loomis Becker,[4] one of three men elected to Congress when Minnesota became a state.

Since Minnesota could only send two, Becker elected to stay behind, and he was promised to have a county named after him.

In 1884, Detroit Lakes had many businesses, including two hotels, a bank, a newspaper, and an opera house.

Detroit Lakes hosts a park dedicated to the Grand Army of the Republic.

The city rededicated the park on April 15, 2015, marking the 150th anniversary of the end of the Civil War and the death of President Lincoln.

Colonel Tom Mortenson and his wife, Pam, sponsored the rededication, representing the Women's Relief Corps, which spearheaded community support for the effort that included new signage for the park and a time capsule to be opened on the 200th anniversary.

It is home to several hundred lakes, many acres of fertile farm land, and forested areas.

Following Black Tuesday and the onset of the Great Depression, Becker County proceeded to voted Democrat in nearly every election for the next half-century, only backing the Republican nominee in nationwide Republican landslides in 1952 and 1972 by Dwight D. Eisenhower and Richard Nixon respectively in the elections from 1932 to 1976, though the Democrat margin of victories were typically modest outside of their nationwide landslides.

Beginning in 1980, Becker County has backed the Republican nominee in every presidential election except for the reelection of Bill Clinton in 1996, and never by huge margins up to and including 2012.

A popular YouTube channel, CBOYSTV films, is headquartered in Becker County.
