Question: Who is the current leader of the party Hartley began leading in 1919? Passage:He was born in St. Johns, Canada East. The son of Edward Hartley Dewart, a Methodist minister who was a staunch advocate of prohibition, the younger Dewart inherited his Liberal politics but broke with his father on the temperance issue becoming a firm opponent of prohibition, a move that would cost him dearly later in life. He studied at the University of Toronto and Osgoode Hall and was called to the Ontario bar in 1887. Dewart set up practice in Toronto and served as crown attorney for York County from 1891 to 1904. He was first elected to the provincial legislature in a 1916 by-election after the death of James Joseph Foy in the Toronto Southwest electoral district, becoming the first Liberal to win a Toronto seat in a quarter century. In 1919, he became leader of the Ontario Liberal Party. He resigned as leader in 1921 due to opposition within his caucus to his anti-prohibitionist stance. He returned to private practice and died at his home near Uxbridge in 1924.

Question: Of the two colonies captured by Philip, which one was established first? Passage:Athens and Macedon had been at war since 356 BC, after Philip's capture of the Athenian colonies of Pydna and Potidea. Shortly afterwards, the Third Sacred War began after the Phocian seizure of the Temple of Apollo in Delphi. Athens allied herself with Phocis, against the other members of the Amphictyonic League. In 354 or 353 BCE, the Thessalians, having been defeated by the Phocians, requested that Philip become archon of Thessaly, to which Philip assented, drawing Macedon into the Sacred War. In 352 BC, Philip's erstwhile ally, the Chalkidian League (led by Olynthos), alarmed by Philip's growing power, sought to ally themselves with Athens, in clear breach of their alliance with Philip. In response, Philip attacked Chalkidiki in 349 BC, and by 348 BC, had completely destroyed the Chalkidian League, razing Olynthos in the process.
