When it opened, the Suez Canal was only 25 feet deep, 72 feet wide at the bottom, and 200 to 300 feet wide at surface. Consequently, fewer than 500 ships navigated it in its first full years of operation. Major improvements began in 1876, however, and the canal soon grew into one of the world's most heavily travelled shipping routes. In 1875, Great Britian became the largest shareholder in the Suez Company when it bought up the stock of the new Ottoman governor of Egypt. 7 years later, in 1882, Britian invaded Egypt, beginning a long occupation of the country.
