Prince George's County Celebrates 300
years of history 1696-1996
FLAGS: LET THEM WAVE HIGH AND PROUD
The simple, yet distinctive Prince George's County flag is a fascinating
blend of history and heraldry dating back to the 11th century. Soon after
the county's founding, it was granted colors for horses and foot soldiers
and a flag consisting of St. George's Cross on a white field. The red cross
of St. George has a long-standing tradition of its own as the symbol of
Christian martyrdom since its first use during the great Crusades.
The county seal in the flag's upper left quadrant did not officially
become part of the flag until 1963. At that time, a special committee
suggested to the County government that the seal be added to "more definitely
establish the colors as uniquely those of Prince George's County." The seal
was designed in 1696 by Charles Beckwith of Patuxent. The coat of arms in
four quarters symbolizes Queen Anne, France and England in the first and
fourth grand quarters; Scotland in the second grand quarter; and Ireland in
the third. The banner below depicts the county motto, "Semper Eadem," which
means "Ever The Same."
The deep history of the Prince George's County flag embodies the tradition
and 300-year history of the county itself. In 1996, more than ever before,
Prince Georgians will have good reason to show their true colors by displaying
the county flag at their businesses and homes. A sub-committee has been
created to specifically handle the strong increase in demand for County
flags. The committee is asking County retailers who presently stock the
flags to bolster their inventories for the Tricentennial, and seeking new
outlets to sell the flags.
Once points of sale are established, the committee will disseminate
information on where flags can be purchased. Any retailers who would be
interested in this effort to "get the flag out," should contact the
Tricentennial Celebration Office at (301)322-1996.
