Which Peaky Blinders character is based on Joseph Kennedy Sr.?

Jack Nelson is the Peaky Blinders character based on Joseph Kennedy Sr.

Nelson appears in the sixth series as a powerful South Boston gangster with political influence and ambitions in the American liquor trade. His connections include President Franklin D. Roosevelt, placing him at the intersection of organised crime, business and politics.

The character reflects Kennedy’s real-world profile without being a direct biography. Joseph Kennedy Sr. was a wealthy businessman, the first chairman of the U.S. Securities and Exchange Commission, and U.S. ambassador to the United Kingdom from 1938 to 1940. The series reworks those political and financial associations into a fictional criminal empire.

A common mix-up is confusing Jack Nelson with Brilliant Chang or Darby Sabini, who are also major criminal figures in the series. Nelson is specifically the American power broker introduced in the final season, while Chang is associated with opium trafficking and Sabini with London’s racecourse gangs.
