Formerly enslaved people in Galveston celebrated after the announcement. Freedmen in Texas organized the first of what became the annual celebration of "Jubilee Day" on June 19. Early celebrations were used as political rallies to give voting instructions to newly freed slaves. Early independence celebrations often occurred on January 1 or 4.
On June 19, 1910, a Father's Day celebration was held at the YMCA in Spokane, Washington, by Sonora Smart Dodd. Her father, the civil war veteran William Jackson Smart, was a single parent who raised his six children there. She was also a member of Old Centenary Presbyterian Church (now Knox Presbyterian Church), where she first proposed the idea. After hearing a sermon about Jarvis' Mother's Day in 1909 at Central Methodist Episcopal Church, she told her pastor that fathers should have a similar holiday to honor them. Although she initially suggested June 5, her father's birthday, the pastors did not have enough time to prepare their sermons, and the celebration was deferred to the third Sunday in June. Several local clergymen accepted the idea, and on June 19, 1910, the first Father's Day, "sermons honoring fathers were presented throughout the city".
In early 1942, the company that employed Doc Goddard (a friend of her mother's husband, Grace McKee Goddard) relocated him to West Virginia.California child protection laws prevented the Goddards from taking Monroe out of state, and she faced the possibility of having to return to the orphanage.As a solution, she married their neighbors' 21-year-old son, a factory worker James "Jim" Dougherty; the wedding took place on June 19, 1942, just after her 16th birthday.
It soon saw a revival as black people began tying their struggle to that of ending slavery. In Atlanta, some campaigners for equality wore Juneteenth buttons. During the 1968 Poor People's Campaign to Washington, DC, called by Rev. Ralph Abernathy, the Southern Christian Leadership Conference made June 19 the "Solidarity Day of the Poor People’s Campaign".
In 2020, Massachusetts Governor Charles Baker issued a proclamation that the day would be marked as "Juneteenth Independence Day". This followed the filing of bills by both the House and Senate to make Juneteenth a state holiday. Baker did not comment on these bills specifically, but promised to grant the observance of Juneteenth greater importance.
