1. The first recorded celebration of Independence Day in Oregon occurred in 1844 at Oregon City. The festivities included a parade, a ceremonial reading of the Declaration of Independence, and a barbecue.

2. In 1859, an Independence Day parade in Salem featured a group of women wearing "bloomers," a then-controversial style of women's clothing that consisted of pants worn under skirts. The sight caused a stir among some spectators and resulted in heated debates about women's rights.

3. During World War II, Oregon played an important role in defending the West Coast from potential Japanese attacks. On July 4, 1942, a blackout was imposed on the state to prevent any possible enemy sightings of ships or other targets along the coast.

4. In 1971, a group of Native Americans organized a protest against the annual Fourth of July parade in Ashland, claiming that the holiday represented a celebration of colonialism and oppression. The demonstration sparked a heated debate about the country's past and present treatment of indigenous peoples.

5. In recent years, Portland has become known for its unusual and sometimes provocative July 4 celebrations. In 2018, one parade featured a giant inflatable blimp of President Trump striking a menacing pose, while in 2020, Black Lives Matter protesters staged a street painting to honor the victims of police brutality.
