His successor Ere (who incidentally was a grandson brought in fair laws and established the guild system for which the Edo people are still known. It is to his credit that the palace system was organized and established from which its present form has evolved.

Orire brought about the primogeniture law, which lasted more than one century. During ogiso Ighido, this law broke down as a result of palace rivalries. It got into a chaotic situation at a time, and this gave rise to the saying that "ogiso will only summon the council meeting whenever there is trouble" (Ogiso Mamie Emwen Ei Fiagba"). This situation remained for nearly two centuries when Ogiso Oriagba re-established the primogeniture laws. This brought stability once more to state. The guild system was re-established, and all the arms of the government were re-kindled.

The stable situation of the state brought about the formation of the Benin Army during the reign of Ogiso Odoligie. A class of people known as "Iyokuo"-the warriors-- was established.

During the reign of Ogiso Ohuede, there was severe inflation. Other pestilences followed. People counterfeited the coins of the realm by bringing illegal money into the country. What happened was that people suddenly discovered a large number of cowries (which was the then known coin or money in use) and after that flooded the country with it. The attendant result was inflation. When Ogiso Obioye came in as ruler, he harnessed the whole currency by nationalizing cowries wherever they were in private hands or with the state. This money became scarce, and its value restored. It is this state of affairs which gave rise to the expression "a valuable article purchased with Obioye's Coin". Ogiso Obioye, therefore, was the first king who reformed the currency.
