Looking for accurate historical or political information from any single source is going to lead to inaccuracies. Every single one has an interest in promoting a certain view of both historic and current events. Usually math or science facts are wrong on Wikipedia simply due to human error. Unless they somehow have bearing on a historic or current event that is contentious. In that case you are back to being unable trust any single source without corroboration wikipedia or otherwise.
