March 8, 1970: Native American protesters and their supporters clashed with military police in an attempt to reclaim Fort Lawton for local tribes.

• The protests were led by Bob Satiacum and by Bernie Whitebear, who would go on to found Daybreak Star Indian Cultural Center in today's Discovery Park.
• Native American activist Leonard Peltier and actress Jane Fonda joined the demonstrations.

March 9, 1995: Washington Secretary of State Ralph Munro joined Gov. Mike Lowry to launch a "Free Lolita!" campaign urging the release of the captive orca locally known as Tokitae, who was taken from Penn Cove off Whidbey Island and later sold to the Miami Seaquarium.

• Despite ongoing protests by activists and several lawsuits, Lolita remained at the Seaquarium until her death last year.

March 11, 1952: Seattle voters defeated a hotly contested proposal to add fluoride to the city's drinking water by an overwhelming margin.
