In 2009 a new leadership group led by Mikhael Nizam Shammas established a new team, which was named the Boston Thirteens.

The club was incorporated as a C corporation (under the name of the "Boston 13s RLFC, Inc.") on Friday, February 13, 2009, and began play in the 2009 AMNRL season.

In 2015, Boston won their first national championship defeating the South Conference champion Atlanta Rhinos 44–12.

In March 2021 the Thirteens resigned from the USARL to become one of the founding teams of the new professional North American Rugby League.

[8] The team was named the 13s reflecting the 13 original colonies of America, the thirteen players on the field in rugby league, plus the fact that the club is the thirteenth RLFC to be founded in the United States.
