Q: Passage: In many Hindu temples, especially in Central India like Maharashtra and South India like Kerala and Karnataka you can find idols of Brahm Rakshas in outer walls and are generally offered pooja, respects and an oil lamp is lit on regular basis in front of their idols. There are many temples, where they are also worshiped as demi-gods, like in Malliyor Temple of Kottayam District of Kerala, it is customary to take permission from Brahma Rakshas before commencing the construction activities. Further, at Thirunakkara Shiva Temple also in Kottayam in Kerala, there is a separate temple for Brahm Rakshasa. There is an interesting story about why the Brahma Rakshas temple was built here. One person called Moose was a great friend of the king. The king was not known for his beauty but his friend Moose, was very handsome. The queen fell in love with this friend knowing which the king ordered his servants to kill Moose. Instead of killing him the King’s servants killed the junior priest of the temple (keezh Santhi). The wife of the priest became a Brahma Rakshas and started troubling every body. So the king built a temple for her. For a long time afterward women did not prefer to enter this temple. Further, it is said that at Madikeri the Omkareshwar Shiva temple was built by king to ward of evil caused by Brahm-Rakshasa. At Shringeri, the Malayala Brahma Temple is of a Brahma-Raskshas.

Q: Passage: Since about 560, the Avars had ruled over large parts of the Pannonian Basin and Carantania southeast of Francia, though in the last decades, the Avar Khaganate had to deal with Bulgarian and Croat incursions. To secure the frontier of his empire and the traffic on the trade routes to the east, Charlemagne allied with Khan Krum of Bulgaria and the Croatian duke Vojnomir, and from 791 launched several campaigns against the Avars, where he, according to the Vita Karoli Magni, encountered only modest opposition. In 796 Carolingian forces under Charlemagne's son Pepin of Italy destroyed the main Avar fortress called the Ring of the Avars and made the Khagan a Frankish vassal, while the remaining Avars retreated behind the Tisza River. The victory is perpetuated by the poem De Pippini regis Victoria Avarica.
