Independence or Birthday for Every Country

The vast majority of the countries on earth became independent after 1800. Only 20 were independent before the start of the 19th century, a mere 10%. By 1900, only 49 or 25% of the world's countries of today were independent.
Many countries became independent following World War II when European powers granted independence to their vast colonial holdings, especially Africa.
