Archaeological evidence of the Bantu people can be found in the  form of Stone Age axes from around 500 BC.

One of the many lands he discovered was  the estuary of the Komo River which they believed resembled the shape of a  cloak. They named it the Gabao, which is Portuguese for cloak and this name,  was later given to the entire country. &nbsp;In 1593 the Dutch visited the country followed  by the French some 35 years later. The first trade between the natives and  <a href=\"http:\/\/www.earth-site.co.uk\/Education\/european-countries.html\">Europeans<\/a> was that of tobacco, and cloth but by the late 18<sup>th<\/sup> Century the main trade had become slavery. Africans were kidnapped from deep  within <a title=\"Gabon\" href=\"http:\/\/www.earth-site.co.uk\/Education\/gabon\/\">Gabon<\/a> and the surrounding area by slavers and then bound and sailed down  the river to the estuary. The mouth of the river was a huge slave market were  European s such as the <a title=\"United Kingdom\" href=\"http:\/\/www.earth-site.co.uk\/Education\/united-kingdom\/\">British<\/a>, <a title=\"France\" href=\"http:\/\/www.earth-site.co.uk\/Education\/france\/\">French<\/a> and <a title=\"Netherlands\" href=\"http:\/\/www.earth-site.co.uk\/Education\/netherlands\/\">Dutch<\/a> would purchase them, mainly  for work in the <a href=\"http:\/\/www.earth-site.co.uk\/Education\/american-countries.html\">America&rsquo;s<\/a>. <\/span><\/p>\r\n<p>&nbsp;<\/p>\r\n  <p class=\"MsoNormal\" style=\"text-align:justify;text-indent:36.0pt;\"><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">By  the 1800&rsquo;s both France and Britain had begun to change their policy on slavery.  On the 4<sup>th<\/sup> of February 1794 the French Revolutionaries passed a law  banning slavery in France and all its colonies. Napoleon Bonaparte revoked the  law eight years later on the 20<sup>th<\/sup> of May 1802 in many of the  colonies in the westbut it was completely outlawed in all their colonies by the  27<sup>th<\/sup> of April 1848. The <a href=\"http:\/\/www.earth-site.co.uk\/Education\/united-kngdom\/\">United Kingdom<\/a> abolished the slave trade  throughout the empire on the 25<sup>th<\/sup> of March 1807 which came into  effect in 1808. In 1833 the Slavery Abolition Act banned slavery giving freedom  to all previously bought slaves within the British Empire. After the final  defeat of Napoleon in 1815 both the Royal Navy and the French Navy began to  actively patrol the western coast of Africa in order to prevent the  continuation of the slave trade.<\/span><\/p>\r\n<p>&nbsp;<\/p>\r\n  <p class=\"MsoNormal\" style=\"text-align:justify;text-indent:36.0pt;\"><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">Through  treaties signed in 1839 and 1841 with French diplomats and leaders in Gabon,  France became a protectorate of the country. Despite the actions of the two  Navies many people attempted to smuggle slaves out of Africa. In 1849 one such  ship was boarded by the French Navy and the slaves freed. These slaves were  released in an area they named &ldquo;Libreville&rdquo; (French for free town) which has become  the capital city of Gabon.<\/span><\/p>\r\n<p>&nbsp;<\/p>\r\n  <p class=\"MsoNormal\" style=\"text-align:justify;text-indent:36.0pt;\"><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">France  had also acquired other territories in Africa including Middle Congo (now the  <a href=\"http:\/\/www.earth-site.co.uk\/Education\/republic-of-the-congo\/\">Republic of the Congo<\/a>), Oubangui-Chari (now the <a title=\"Central African Republic\" href=\"http:\/\/www.earth-site.co.uk\/Education\/central-african-republic\/\">Central African Republic<\/a>) and  <a title=\"Chad\" href=\"http:\/\/www.earth-site.co.uk\/Education\/chad\/\">Chad<\/a>. On the 15<sup>th<\/sup> of January 1910 France incorporated these  countries and Gabon into French Equatorial Africa (or Afrique Equatoriale  Francaise (AEF)). These countries played a pivotal role for the Free French  forces during World War II. <\/span><\/p>\r\n<p>&nbsp;<\/p>\r\n  <p class=\"MsoNormal\" style=\"text-align:justify;text-indent:36.0pt;\"><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">By  the end of Word War II the Anti-Colonial Movement in France was at full force  and on the 27<sup>th<\/sup> of October 1946 the French Fourth Republic changed  the constitution which changed all colonies of the French Empire into the  French Union. In the French overseas territory of <a title=\"Algeria\" href=\"http:\/\/www.earth-site.co.uk\/Education\/algeria\/\">Algeria<\/a> the majority of the  population were looking towards complete Independence from France and on the 1<sup>st<\/sup> of November 1954 war broke out between the National Liberation Front and French  Forces. But independence was not wanted by the entire population and in 1958 approximately  1 million of the countries 9 million inhabitants marched in the capital city,  Algiers, against independence form France. General Charles de Galle was  recalled to power and he dealt with the situation by ordering a referendum be  held in all the countries of the French Union. On the 28<sup>th<\/sup> of  September 1958 all the countries of France voted for a change to the  constitution. It gave all overseas territories until the 4<sup>th<\/sup> of  February 1959 to choose one of three options:-<\/span><\/p>\r\n<p>&nbsp;<\/p>\r\n  <ol>\r\n    <li><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">To remain a French Overseas Territory  (Governed by elected localised group assemblies)<\/span><\/li>\r\n    <li><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">To become a member state of the French  Community<\/span><\/li>\r\n    <li><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">Become an Overseas Department<\/span><\/li>\r\n  <\/ol>\r\n<p>&nbsp;<\/p>\r\n  <p class=\"MsoNormal\" style=\"text-align:justify;\"><span style=\"font-family:'Verdana','sans-serif'; font-size:9.0pt; \">Gabon chose to become a  Member State of the French Community and on the 4<sup>th<\/sup> of June 1960 new  changes to the constitution gave Member States the right to full independence.  On the 17<sup>th<\/sup> of August 1960 Gabon became fully independent from  France (the last member of French Equatorial Africa to do
