I want to know the answer to the following question:
War was started with the Ottomans when?
All the background I'm provided with is that "The first of these revolts began on 6 March 1821 in the Danubian Principalities under the leadership of Alexandros Ypsilantis, but it was soon put down by the Ottomans.". Is that enough to answer the question?
Answer: no
