To point it looked exactly like Madara?
I have any doubts that he is able to control Yagura but Yagura was mizukage right on the begining of the war, i think it's kinda obvious that the whole timeline is pretty much f**cked up.
On this time Nagato was younger since it was on the third war that he lose his parents and Nagato was just a kid when Obito goes out Nagato was a teenager much like Naruto's current age, and despite in peace there were some conflicts like the village of the rain, which Jiraiya pretty much described that he heard that he died on one of those "wars".
Thats the problem with the time of the series, we can only use the age of characters and some events as to how much time actually passes and what occurs and when. There is no yearly dating system, we only get an approximation of time that passes but not the actual span of it.
If we go by the whole series, we only know these spans of time that occur:
1,000 or so years between the Sage and the village era, the tailed beasts are hundreds of years old, this length of time is also for the "evolution" of ninja, its a given set of time for the tailed beasts to grow, the bloodlines of ninja to expand and change, and the passage of time for the 5 great nations to have been established at one point during this period of time along with technology (or whatever technology exists in this universe) to pass and develop. The 5 nations existed before the ninja villages. We also know that there was a great span of time due to others like the elder toad sage being 1,000 years old and fukasaku himself being 800 years old. Jiriaya even said that the nine tails appeared several times in human history, generally whenever hate festered and human malice was at its height.
The era of the ninja villages: we only know that the era our story takes place in is around 70-85 years in the era. This is due to Hiriuzen's age (69) and Kakuzu (91) basically the villages are older than 60 but younger than 90. The village was around with Hashirama and Tobirama too, but they had to be about mid thirty to forty when they died. The first war had to have occurred for at least 5 years too, Tobirama died in the first war but had to be hokage for a small amount of time because Hiruzen was a child (10-12) when he was trained by both senju brothers, but on the night of his death Hiruzen had to be at least 17 when he became hokage and he was hokage for a long time until he was at least 57. Kakuzu was from the warring clan era but lived unnaturally long due to his earth grudge fear techniques.
The only real sense of time we know of is:
Month break in the chunin exam between preliminary and finals.
3 month gap between Sasuke running away and Naruto leaving with Jiriaya (This passage of time is canon as even for one simple panel space, Tsunade says Sakura had come far in that short time during medical training).
The timeskip 2-1/2 years
At least 6 months from the start of shippuden to the "death" of orochimaru by Sasuke.
Past events based on the age of certain characters like Jiriaya, Kakashi, and so on.
Problem is we never get even a notion of a month for these events. Thats why we are left with approximations and estimates.
