After he came to power, he began his brutal raid, to once again unite Ethiopia and put her under one king as it was for the previous 3,000 years. After fighting several battles in 1855 he united Ethiopia and became Emperor Tewdros, King of kings of Ethiopia. His main vision was not just to unify this Christian empire but it was also to industrialize her.
Throughout his emperorship he began to fight the Ethiopian Orthodox Church because of their continuous obstacle to industrialize Ethiopia. However he was also a devoted orthodox Christian. His hatred and suspicion was also on foreign missionaries of catholic whom he despised the most and Protestants whom he allowed in very few numbers. Once when a group of German missionaries arrived at his court to pay their respect he asked them if they know how to make firearms. They replied they don’t, and they were there because they were “men of God to preach the gospel”. He angrily replied that Ethiopia already have more than enough priests to preach the gospel. He ended up forcing the missionaries to make him a firearm by holding them as hostages. Luckily, they built him a canon, which they called it “Sebastopol” but he was not satisfied so he decided to imprison them for more time. Even though he does all that wrongdoings he was still a very religious person and his great dream and goal for a long time was “to drive the Turks out of Jerusalem”; which is why today he is called husband of Ethiopian, fiancĂ© of Jerusalem.
The emperor deep resentment towards the church and his angry attitude to his people in addition to rebellion through his far flung kingdom began to weaken him. But, most of all it was his stubborn attitude and miscommunication with the English which ended his trembling empire. He wrote a letter to queen Victoria requesting for firearms and military personnel, to assist his growing army. But his letter never reached the queen because of the lower officers disregard and their though of him as a barbaric African monarch, which they letter regretted when he imprisoned and held hostage every missionary and every letter man they sent. When the situation got worst his letter was searched and found. Soon Queen Victoria replied. But her reply didn’t satisfy him. The British parliament decided to send 32,000 British and Indian armies to set free over dozen of missionaries, captains, and letter men.
The battle started on April 10 1868. Even though his few loyal Ethiopian armies fought devotedly they were outnumbered by the sophisticated British army which won the war after two days. After seeing his defeat from mountain top emperor Tewodros II felt sad because his own fellow citizens betrayed him, but it is said that he felt very sorry that he could no longer drive out the Turks from Jerusalem. Finally when he heard the British army has got to the top of mountain, he shot himself with a pistol queen Victoria had sent him. In Ethiopia his suicide was told to generations as pride and dignity for not giving up himself for captivity of a foreign force.
