1. In 1630, the Puritan colonists in Massachusetts Bay Colony purchased a large tract of land from Native Americans, including the area that would become the city of Lynn. This purchase was one of several controversial land deals that contributed to conflicts between the colonists and the indigenous peoples of the region.

2. On July 28, 1730, construction began on the Old South Meeting House, a historic church in Boston that would become one of the most important gathering places for colonists during the years leading up to the American Revolution. The church is now a museum and National Historic Landmark.

3. In 1856, suffragist and abolitionist Lucy Stone became the first woman from Massachusetts to earn a college degree, when she graduated from Oberlin College in Ohio. Stone later became a prominent speaker for women's rights and helped organize the first National Woman's Rights Convention in Worcester, Massachusetts in 1850.

4. On July 28, 1931, the Boston Braves (now the Atlanta Braves) played their first game at Braves Field, a newly-built stadium in Boston's Allston neighborhood. The Braves would play at the stadium for more than 40 years before moving to Milwaukee in 1953.

5. In 2010, the Massachusetts Bay Transportation Authority (MBTA) launched an innovative bike-sharing program called "Hubway", which allowed users to rent bicycles from docking stations located throughout Boston, Cambridge, and several other cities in the region. The program was later rebranded as "Blue Bikes" and continues to be popular with commuters and tourists alike.
