The Battle of the Diamond takes place near Loughgall, County Armagh, between the Protestant Peep o’ Day Boys and the Catholic Defenders. The violent clash results in the deaths of around 30 Defenders. In the aftermath, the victors go on to found the Loyal Orange Institution — later known as the Orange Order — with the declared aim of defending “the King and his religion.” This event marks a turning point in the sectarian tensions of 18th-century Ireland.
