Yes, historically, some monks in various cultures did use glaives or polearms as part of their martial practices and self-defense. The term "glaive" refers to a type of pole weapon with a blade attached to a long pole, often with a curved or hook-like shape.

In certain martial traditions, particularly those originating from East Asia, there were monastic orders that incorporated combat training as part of their discipline. These warrior monks, such as the warrior monks of Shaolin Temple in China or the Sohei in Japan, were known for their proficiency in martial arts and the use of various weapons, including glaives.

Glaives were effective weapons for monks as they provided reach and versatility in combat. They could be used to keep opponents at a distance, hook and disarm adversaries, and strike with slashing or thrusting attacks. The curved or hooked shape of some glaives allowed for unique techniques and maneuvers.

It is worth noting that not all monks used glaives or practiced martial arts. Monks in different cultures and religious orders pursued various paths and focused on different aspects of spiritual practice, with some emphasizing non-violence and pacifism.

However, in specific historical contexts, such as certain Buddhist or Taoist monastic traditions, there were instances where monks received combat training and employed weapons like glaives for self-defense or protection of their monastic communities.

As with any historical topic, the specific practices and traditions of warrior monks can vary depending on the time period, geographical location, and individual orders. It is always important to consider the specific historical context when discussing the weapons and practices associated with any particular group of monks.
