Who was officially designated as Chief of Constabulary in 1901?

The designation of Chief of Constabulary in 1901 is attributed to Henry T. Allen. This appointment was significant in the context of the establishment of law enforcement in the Philippines following the Spanish-American War and the subsequent American colonial period. Allen's role involved overseeing the transition and reorganizing the Philippine Constabulary, which was a crucial component of the emerging government structure.

His leadership focused on professionalizing the police force, implementing a system of training for law enforcement officers, and integrating the Constabulary into the overall governance of the islands. This period marked a pivotal moment in shaping the modern law enforcement framework in the Philippines, helping to establish order and bring stability to the region during a time of considerable change.
