Events of historical significance, such as important military victories or other nation-building events also provide the impetus for festivals. An early example is the festival established by the ancient Egyptian Pharaoh Rameses III to celebrate his victory over the Libyans. Festivals contribute immensely to feelings of social cohesion. Many such celebrations focus on cultural or ethnic topics and seek to inform community members of their traditions. They involve community elders sharing stories and experiences; setting templates for maintaining unity among families.
