I guess I have two flags because I was born in America and I live in Canada.....
50 stars=50 states, 13 stripes =13 colonies. To go into more historic detail:
-On June 14, 1777, in order to establish an official flag for the new nation, the Continental Congress passed the first Flag Act: "Resolved, That the flag of the United States be made of thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new Constellation."
-Act of January 13, 1794 - provided for 15 stripes and 15 stars after May 1795.
-Act of April 4, 1818 - provided for 13 stripes and one star for each state, to be added to the flag on the 4th of July following the admission of each new state, signed by President Monroe.
-Executive Order of President Taft dated June 24, 1912 - established proportions of the flag and provided for arrangement of the stars in six horizontal rows of eight each, a single point of each star to be upward.
-Executive Order of President Eisenhower dated January 3, 1959 - provided for the arrangement of the stars in seven rows of seven stars each, staggered horizontally and vertically.
-Executive Order of President Eisenhower dated August 21, 1959 - provided for the arrangement of the stars in nine rows of stars staggered horizon tally and eleven rows of stars staggered vertically.
Red and white are Canada's nationl colours and the maple leaf is the countries symbol based on many things throughout history:
-In 1834, Ludger Duvernay is reported to have proposed the maple leaf as an emblem of Canada when the Société Saint-Jean-Baptiste was founded on June 24 of that year.
-In 1836, Le Canadien, a newspaper published in Lower Canada, referred to it as a suitable emblem for Canada.
-In August 1860, at a public meeting held in Toronto, the maple leaf was adopted as the national emblem of Canada for use in the decorations for the Prince of Wales' visit.
-In 1867, Alexander Muir, a Toronto schoolmaster and poet, composed the song The Maple Leaf Forever.
-In 1914, many Canadian soldiers wore the maple leaf on their military badges, and it was the dominant symbol used by many Canadian regiments serving in the Great War (World War I).
-In 1939, at the beginning of World War II, numerous Canadian troops once again used the maple leaf as a distinctive emblem, displaying it on regimental badges and Canadian army and naval equipment.
