Many countries have a uniting motto. The motto of the United Kingdom is "God and my right," the United States is "In God we Trust," while the French motto is "Liberte, Egalite, Fraternite," Uganda's is "For God and My Country," while Tanzania's and South Africa's are "freedom and unity" and "diverse people unite" respectively.
Interestingly, the citizens somehow gravitate toward their national motto. Our motto "Harambee" meaning pulling together or signifying a spirit of cooperation, is found in our Coat of Arms.
