This story starts in 1802.
That year Napoleon sent a Polish legion of 5000 to join the French forces in Saint-Domingue to put down the Haitian slave rebellion. The Poles had chosen to support Napoleon to receive French support in restoring their own country’s independence from Prussia, Russia and Austria, who had divided Poland between them.
But after arriving in Saint-Domingue, and being thrown straight into battle, the Poles quickly learned that the French were actually trying to brutally crush an uprising by enslaved Africans fighting for freedom from their white masters. And many joined the ranks of the revolutionaries against the French.
Following the decisive defeat of the French and Haiti’s declaration of independence on 1 January 1804, the country's first ruler, Jean-Jacques Dessalines, took steps to protect the surviving Poles and while the 1805 Haitian Constitution banned white people from owning land or holding citizenship, Dessalines explicitly exempted the Poles and around 500 settled in Haiti.
Over two centuries later, the Haiti kit for their first WC appearance in 52 years seems to feature a Polish flag in the bottom left, a possible tribute to those Poles who supported their struggle and settled in Haiti.
Fascinating, in a year that Poland will not be represented by their own national team.
