Which Arab states invaded after Israel declared independence in 1948?

Following the declaration of independence by Israel on May 14, 1948, forces from five Arab nations invaded the newly established state on May 15, 1948. These countries were:

• Egypt
• Jordan (then known as Transjordan)
• Iraq
• Syria
• Lebanon

This military intervention marked the beginning of the conventional phase of the 1948 Arab-Israeli War, which followed a period of civil conflict within the British mandate of Palestine. The war concluded with a series of armistice agreements in 1949, though no formal peace treaties were signed between Israel and these neighboring states at that time.12
