What is band together? How to use in English

The phrase "band together" originates from the Middle English word "bande," which meant a group or company of people. This word is related to the Old English "band," which had a similar meaning. The term "bande" gained wider usage in the 14th century, largely due to the increase in the formation of mercantile guilds or trade associations among craftspeople and merchants. In these guilds, members banded together to set standards for their craft or trade, regulate prices, and provide mutual support. The term "band together" became a common phrase to describe this action, indicating a sense of unity and cooperation. The word continued to be used in this way throughout the Renaissance and into the modern era, where it has retained its meaning of working in unity for a common goal, whether it be commercial, political, or social. The expression has gained common usage in various contexts, including in business, sports, and community organizations.
