The 2011 Belgium 2 euro commemorative coin marks the centenary of International Women's Day, an occasion first celebrated in 1911 to advocate for women's rights and equality. The national side of the coin features portraits of Isala Van Diest and Marie Popelin. Isala Van Diest holds the distinction of being the first female physician in Belgium, while Marie Popelin was the country's first female doctor of law. By honouring these two pioneering figures, the design highlights their significant contributions to the advancement of women's professional and legal rights within Belgian society. Their inclusion serves as a tribute to the historical struggle for gender parity and the progress achieved over the preceding century. This coin was issued in 2011 with a mintage of 5,000,000 pieces.
