Then a number of paragraphs but the skill being to keep coming back to your point. eg 'Revolutionary ideology was circulating in Russia and is often cited as a major cause of the Romanov's removal (develop slightly to mention lenin & co). However, these ideas were current across Europe and the West, and although adherents promoted the idea of revolution it did not occur widely. In Russia, revolutionary ideas needed the addition of the hardship and humiliation of the war to spur effective action.'
Then in last para ' In conclusion, while the complex web of events alluded to above were vital contributors to the fall of this royal dynasty, the disastrous involvement of Russia in the war gave the additional impetus needed to bring about the czar's abdication and his nominated successor's refusal to accept the crown, so ending Roamnov rule.'
