The Samurai Archives has another brilliant podcast on Nobunaga. This time, the podcast explains Nobunaga's retainers and how unorthodox it was during his reign. http://www.theshogunshouse.com/2014/02/ep81-nobunagas-motley-crew.html
There were several key points why Nobunaga was successful
- He had few or none clan elders which freed him up.
- Old families such as the Takeda and the Uesugi were more traditional and restrained freedom.
- Nobunaga was able to delegate authority to his captains. Which made waging war on a national scale much easier. If Nobunaga led the front on every campaign, he would have never had the chance to unify the country. However, when he did lead the front, it was brutal, bloody, and nasty.
Tenka no tame!
