July 30, 1619
First legislative assembly in America
In Jamestown, Virginia, the first elected legislative assembly in the New World--the House of Burgesses--convenes in the choir of the town's church.
Earlier that year, the London Company, which had established the Jamestown settlement 12 years before, directed Virginia Governor Sir George Yeardley to summon a "General Assembly" elected by the settlers, with every free adult male voting. Twenty-two representatives from the 11 Jamestown boroughs were chosen, and Master John Pory was appointed the assembly's speaker. On July 30, the House of Burgesses (an English word for "citizens") convened for the first time. Its first law, which, like all of its laws, would have to be approved by the London Company, required tobacco to be sold for at least three shillings per pound. Other laws passed during its first six-day session included prohibitions against gambling, drunkenness, and idleness, and a measure that made Sabbath observance mandatory.
The creation of the House of Burgesses, along with other progressive measures, made Sir George Yeardley exceptionally popular among the colonists, and he served two terms as Virginia governor.
