Hi.
What's the measning of 'lofty' in the following quote?

“I, the sultan of sultans, and the strongest ruler, the loftiest king who defeats the kingdoms around the world, and the shadow of Allah in the Earth, am the son of Sultan Selim who is the son of Sultan Beyazid, Sultan Suleiman, Caesar of Rome, the sultan of Mediterranean Sea and Black Sea, and Thrace, and Anatolia, and Karaman and the City of Dulkadir and Diyarbakir and Kurdistan, and Iran and Damascus and Aleppo and Egypt and Mecca and Medinah and Jerusalem and the whole Arab land and Yemen and many more lands that our lofty ancestors conquered with their crushing powers and I conquered with my fire-scattering sword --- You, the king of province France, Francis.......”

Does it differ from 'grandiest' ?

Thanks in advance
