History of Friedrich II of Prussia, Volume 03 by Thomas Carlyle

The First Friedrich's successor was a younger son, Friedrich II.; who lasted till 1471, above thirty years; and proved likewise a notable manager and governor. Very capable to assert himself, and his just rights, in this world.

The Teutsch Ritters were an opulent domineering Body in Sigismund's early time; but they are now come well down in Friedrich II. 's! And are coming ever lower. Sinking steadily, or with desperate attempts to rise, which only increase the speed downwards, ever since that fatal Tannenberg Business, 15th July, 1410. Here is the sad progress of their descent to the bottom; divided into three stages or periods: --
