In about 260 AD, the fall of the Agri Decumates territory north of the Rhine transformed today's Switzerland into a frontier land of the Empire. Repeated raids by the Alamanni tribes provoked the ruin of the Roman towns and economy, forcing the population to find shelter near Roman fortresses, like the Castrum Rauracense near Augusta Raurica. The Empire built another line of defense at the north border (the so-called Donau-Iller-Rhine-Limes), but at the end of the fourth century the increased Germanic pressure forced the Romans to abandon the linear defence concept, and the Swiss plateau was finally open to the settlement of German tribes.

In what year did the fall of the Agri Decumates territory transform today's Switzerland?
Answer: about 260 AD

The Bengali Renaissance refers to a social reform movement during the nineteenth and early twentieth centuries in the Bengal region of India during the period of British rule dominated by English educated Bengali Hindus. The Bengal Renaissance can be said to have started with Raja Ram Mohan Roy (17721833) and ended with Rabindranath Tagore (18611941), although many stalwarts thereafter continued to embody particular aspects of the unique intellectual and creative output of the region. Nineteenth century Bengal was a unique blend of religious and social reformers, scholars, literary giants, journalists, patriotic orators, and scientists, all merging to form the image of a renaissance, and marked the transition from the 'medieval' to the 'modern'.

With whom did the Renaissance movement begin?
Answer: Raja Ram Mohan Roy
