The Boer War was basically very unpopular with every other European country. While none of them got to the point of wanting to declare with the UK over the matter, it was generally seen as illegitimate Imperial overreach by Britain. They did however turn a blind eye to their own citizens traveling to South Africa to volunteer to fight alongside the Boers. There were thousands of Europeans fighting as volunteers in South Africa, including Scandinavians, French, Germans, Russians, Italians and even Irish. One good example of a foreign volunteer was Russian capitalist Alexander Guchkov, who fought under General Smuts and later went on to become the Russian Minister of Defense. Another was the Comte de Villebois-Maureil, a French Colonel and aristocrat who led a large unit of foreigners and died fighting an overwhelming British force. People like Guchkov and the Comte de Villebois-Maureil were very much members of their respective country's elites, and represented those countries' views regarding the Boer War - that it was an illegitimate war being fought by the British for bad reasons against people who just wanted to maintain their independence.
