What are some symbols of peace?

There are several different symbols that are recognized as peace signs world wide. The most popular is the circle with a line through the middle and two smaller branches emanating from the center to the edge of the circle about 35 degrees out from the line on either side. This was originally the symbol for nuclear disarmament and became a symbol for peace worldwide.

Another symbols for peace is the V made with a hand by folding in all fingers except the forefinger and the middle finger. This V stands for "Victory" in many places, but is also known as a symbol of peace because of the peace that was brought about in Europe and Asia at the end of World War 2.

In addition to these signs of peace, the Dove and the Olive Branch are also signs of peace which date back thousands of years to Biblical Times. There are other signs of peace such as flags and symbols as well, but these are the most prominent.
