The flag of Serbia is represented by three equal horizontal stripes of red (top), blue, and white — the Pan-Slav colors representing freedom and revolutionary ideals; charged with the coat of arms of Serbia shifted slightly to the hoist side; the principal field of the coat of arms represents the Serbian state and displays a white two-headed eagle on a red shield; a smaller red shield on the eagle represents the Serbian nation, and is divided into four quarters by a white cross; interpretations vary as to the meaning and origin of the white, curved symbols resembling firesteels or Cyrillic "C's" in each quarter; a royal crown surmounts the coat of arms.
