Again I struggled a little with the theme, apart from ones I've shown previously and the more obvious queens and heads of state. In the nick of time, along came a lovely card from Poland with lovely stamps, one showing the author and activist Maria Konopnicka.
Maria Konopnicka (1842-1910) was a poet and novelist but also campaigned for women's rights and for Polish independence. Prussia, Russia and the Habsburgs had divided up Poland and it wasn't until after World War I that an independent republic was established. She is very highly regarded in Poland for all her works.
