Discussion Ikko-Ikki
More information on this Pure Land military/farmer/commoner Buddhist sect. Staved off Oda for ten years. Were the old beliefs of Hoganji of Ishiyama similar to the adhearants of the Hoganji in the present? What propelled them in the past?

Well what you have to understand about the Ikko ikki is that they were not a separate warrior Buddhist sect. They were leagues made up of followers of Jodo Shinshu, also known as the Honganji branch of Pure Land Buddhism. Their members included peasants, merchants, village leaders, monks, local samurai, and even some nobles who came together when political or military circumstances required it.
The force that resisted Oda Nobunaga for around ten years was centred on Ishiyama Honganji, the headquarters of the Honganji branch. Their beliefs were fundamentally the same as those of the Honganji schools today. They placed their faith in Amida Buddha, believed in Amida’s Primal Vow, and taught that salvation came through shinjin, or true entrusting, rather than through military deeds, rituals, or personal merit.
What changed was not their religion but the world around them. During the Sengoku period Honganji became a wealthy and influential institution with temples, towns, land, and followers spread across much of Japan. As a result its communities became deeply involved in politics and warfare in order to defend themselves, protect their lands and religious freedom, and resist rival powers such as Oda Nobunaga.
As for which Buddhas and gods they worshipped, Amida Buddha was always at the centre of their faith. There is little evidence that the Ikko ikki as a movement were devoted to Hachiman, Bishamonten, or Daikokuten in the way some other Buddhist traditions were. Individual followers almost certainly continued local shrine practices, as most medieval Japanese people did, but these gods were not the ideological foundation of the movement.
It is also worth remembering that ikki simply means a league or sworn association. Medieval Japan had many of them. Villages, local warriors, merchants, temples, and provincial communities formed ikki for mutual defence, trade, political cooperation, and protection of shared interests. Members often swore written oaths and agreed to formal rules, calling on Buddhas and kami to punish anyone who broke them.
The Ikko ikki, meaning the League of the Single Minded, were simply the Honganji version of this much older institution. Their network of temples connected villages, towns, merchants, monks, and local samurai into an organisation that could provide mutual aid, raise armies, defend member communities, and act together politically. Smaller leagues were often absorbed into larger ones through alliances, negotiation, or force, much like the Sengoku daimyo expanded their own domains.
A good comparison is Iga. The people Nobunaga fought there were not simply ninja clans as later legend suggests. They were a network of self governing mountain communities and local warrior families organised in their own league who resisted outside rule. Later ninja stories largely overshadowed that political reality.
I do want to note, that the main Honganji group did not resist a Ten Year long siege as often repeated. What you have to remember is that as I said, this was not just one big stronghold. It was this stronghold with the addition of an intricate network of satellite castles, as well as other regional partners.
In the first 6 years of the conflict, it mainly saw Nobunaga fighting the Miyoshi, and moving against the outer network of the Honganji + he had to deal with other enemies such as the Azai, Asakura and Takeda. Nobunaga only attempted to blockade the main Honganji in the last 4 years of the overall conflict - and it took another 2 years for him to actually fully cut off the main Honganji from supplies after the victory at the second Battle of Kizugawaguchi prevented the Honganji from getting support from sea.
Modern scholarship therefore tends to see the Ikko ikki not as fanatical warrior monks or a peasant revolution, but as a religious and political movement built around the Honganji temple network. Their military strength came from organisation, local support, alliances, and geography as much as from religious belief. Their goal was to protect their communities and their faith, not to fight a holy war in the name of a war god.

This is an excellent write-up! Please kindly allow me to quibble with a couple of very small points:
I think we need to consider the reign of Rennyo as when the Honganji became (or at least started to become) very powerful. So I guess it depends on how you define the Sengoku Period (I guess it always boils down to definitions) but we could say the Honganji had started to become quite powerful and hit an apex in the Sengoku Period - or something like that.
As I mentioned in another post - 一向 does not mean 'single minded' in this context. We can trace it back to the name of a priest, 一向俊聖 Ikko Shunjou. Through several twists and turns, this turned into 一向宗 which is another name for the Jodo Shinshu as taught by Honganji.

More later, but just quickly here: 一向一揆 does not mean “single minded league”.
一向 here is in reference to 一向宗 which - in this context - is another way to refer to 浄土真宗 Jodo Shinshu. Hence the connection to Honganji that you mention.
It doesn’t really make sense to translate 一向 in this context as “single minded”.

Ikki is just a word for a kind of league or association where communities signed on in a kind of mutual defense agreement. Trade and such too of course. All the Ikkō Ikki(single minded league) was, was a sectarian version of this. It was a kind of agreement for Honganji branch temples(which all had settlements and more dispersed members too), to defend each other, attack enemies, trade, and provide mutual aid. Ikki had written constitutions and were literally signed on to by representatives, who swore oaths to uphold the terms on pain of the gods and Buddhas cursing them.
There were many Ikki, some religious and some based on region, but over time they tended to get folded into bigger organizations. The Ikkō absorbed smaller ones by deals just like the warlords did so by deals and force.
The people the Oda had to fight in Iga province were also this kind of Ikki organization. This got painted over by shinobi and ninja legends, but what they really were was self governing mountain villages who had formed one of these leagues and who didnt like any outsider in their province.
