The Thai alphabet is derived from the Old Khmer script, which is a southern Brahmic style of writing derived from the Pallava script was developed under the Pallava dynasty of Southern India around the sixth century CE.

Daniel, the fourth and youngest son of Prince Alexander Nevsky—famous in the history of the Russian State and the Russian Orthodox Church—and his second wife, Princess Vassa, was born in 1261 in Vladimir, the capital of the Great Vladimir-Suzdal principality.

One of the most junior princes in the House of Rurik, Daniel is thought to have been named after his celebrated relative, Daniel of Galicia.

His father died when he was only two years old.

Of his father's patrimonies, he had received the least valuable, that of Moscow.

When he was a child, the tiny principality was being governed by tiuns (deputies), appointed by his paternal uncle, Grand Prince Yaroslav III.

Daniel has been credited with founding the first Moscow monasteries, dedicated to the Lord's Epiphany and to Saint Daniel.

King Rudolph had in December 1282 vested his sons with the Austrian and Styrian duchies, which he had seized for the House of Habsburg from King Ottokar II of Bohemia in 1276.

However, in the Treaty of Rheinfelden on June 1, 1283 Rudolph II has to relinquish his share in favor of his elder brother Albert.

In compensation, his father appoints him "Duke of Swabia”—a largely honorific title, as the former stem duchy had been in long-term disarray after the last Hohenstaufen duke, the underage Conradin, was killed in 1268.

In Swabia, the former Counts of Habsburg only hold various smaller home territories, later summed up as Further Austria, of which Rudolph II will never actually obtain.
