What type of allusion is king making when he refers to the boston tea party

In our own nation, the Boston Tea Party represented a massive act of civil disobedience

The Boston Tea Party was a political and mercantile protest by the Sons of Liberty in Boston, Massachusetts, on December 16, 1773.[1] The target was the Tea Act of May 10, 1773, which allowed the British East India company to sell tea from China in American colonies without paying taxes apart from those imposed by the Townshend Acts. American Patriots strongly opposed the taxes in the Townsend Act as a violation of their rights. Demonstrators, some disguised as Native Americans, destroyed an entire shipment of tea sent by the East India Company.
