What started the pledge?

The pledge typically refers to a commitment or promise made by individuals or groups to uphold certain values or principles. The origins of such pledges can vary widely depending on the context, such as the Pledge of Allegiance in the United States, which was created in 1892 to promote patriotism and unity among citizens. In a broader sense, pledges often emerge from movements or events that seek to foster solidarity, accountability, or support for a cause.
