The keyword phrase "Patriots' Day" functions as a proper noun, referring to the specific name of a commemorative event. India does not have a national public holiday by this name. The observance is regional, celebrated specifically in the state of Manipur on August 13th each year.
This date was chosen to commemorate the historical events of the Anglo-Manipur War of 1891. On August 13, 1891, Manipuri prince Bir Tikendrajit Singh and General Thangal were publicly hanged by the British authorities for waging war against the British Empire. The day serves as a solemn occasion to honor their sacrifice and that of other heroes who fought to defend Manipur's sovereignty.
The observance in Manipur is distinct from other national commemorative days in India, such as Martyrs' Day (Shaheed Diwas), which is observed on different dates to honor various national freedom fighters. It is also entirely separate from the Patriots' Day celebrated in the United States on the third Monday of April, which marks the anniversary of the first battles of the American Revolutionary War.
