Sure
I haven't really revised the boer war yet so you will have to bear with me when I get confused
Right, back in Gladstone's foreign policy there was an issue with south Africa if you remember (which was the first boer War) and the confusion over the convention of Pretoria and suzerainity (sp?) led to the 1899 boer war.
In 1884, huge gold deposits were found in the transvaal which meant uitlanders came flooding in to exploit the newly found gold. Cecil Rhodes who was pm for cape colony (a British territory in South Africa) along with colonial secretary chamberlain thought Britain should take firm control of the transvaal.
So..this led to the jameson raid that you were talking about
1895- Dr jameson (brit living in bechuanaland) invaded the transvaal with 500 men hoping the uitlanders would revolt with him because they were heavily taxed and had no voting rights so thought they'd want a new government too. But poor old jameson had no support and was imprisoned within days.
Now, the boers blamed the British government for this because they assumed jameson would have had permission from the government to invade.
Britain went to war in 1899 because of the gold reserves, their wish to cement their position in South Africa and the aggression between the president of the transvaal and British officials.
Milner (high commissioner for south Africa) was aggressive and wanted the uitlanders to have voting rights. But kruger (transvaal President) didn't want the British telling him what to do. The two met in 1898 after a boer policeman had shot a British worker and was acquitted without trial. kruger was still very stubborn about immigrant's rights. Milner stationed troops around the transvaal borders. He refused to remove them so kruger declared war.
Right, hope that long jumble makes sense :P sorry for the lack of detail, is there anything else?
