23. of March. Day of the sea.
March, 23rd is a special day in Bolivia since 1879. On this day Bolivia lost the province Litoral to Chile. The loss of a province is not really a problem for this country. Bolivia has been double the size. Nevertheless, the province Litoral was the only access to the sea.
At the anniversary the military arrays in enire Bolivia and the local authorities conjure the Bolivian people that their country would be so much better if they only had access to the sea. As simple as that.
