Saya mau tau Ruhr dari Liga Bangsa. Jelaskan dalam bahasa melayu

Under the Treaty of Versailles, Germany had to pay reparations. They could pay in money or in goods at a set value; however, in 1922 Germany was not able to make its payment. The next year, France and Belgium chose to act upon this, and invaded the industrial heartland of Germany, the Ruhr, despite this being in direct contravention of the League's rules. With France being a major League member, and the United Kingdom hesitant to oppose its close ally, nothing was done in the League despite the clear breach of League rules. This set a significant precedent – the League rarely acted against major powers, and occasionally broke its own rules.
