The major obstacle to Islamic expansion in India was the presence of the Rajputs, a traditional patrilineal clan/warrior ruling class.
They WOULD HAVE been treated with the same consideration as others, but inevitably their treatment was harsh, simply because they refused to accept Roman rule for long, and kept rebelling. Around the year 66, Agrippa, nominally king of the jews, delivered a great speech warning the Jews and pleading with them not to start an insurrection. Among other things, he pointed out that if they rebelled, their holy city and Temple might be destroyed, since by "sparing these things up till now, the Romans have received no thanks at all."
Roman suppression of the various jewish revolts was often brutal, and led to great loss of life. Many rebels were killed in action or crucified during the various insurrections between 64 BCE and 135 CE, when the last one was put down. Ignoring agrippa proved very costly, since jerusalem and its temple were indeed destroyed. During Trajan's time, many rebels in the diaspora were killed, in cyprus etc. The crushing of the bar kochba revolt of 132-135 is said to have cost half a million jewish lives. Moreover, for nearly a century after 135, jews couldn't even live in jerusalem.
Besides the repercussions of rebellion, jews were penalized for not worshipping the deified caesars. There was a special tax, the fiscus judaicus, levied on them alone.
The Germans hated the Treaty of Versailles due to the harsh terms imposed on her, especially the reparations, the military and territorial losses. Firstly, the Germans resented the reparations payments. They wereforced to pay £6.6 billion as compensation to the victorious nations.
