In Róma Æterna, the second volume of Ørberg's Lingua Latína per sé illustráta, in a chapter adapted from Eutropius I.9–III.6, on page 181 we find the following sentences:
Verum dignitás tribúnórum mílitárium nón diú persevérávit. Nam post aliquantum núllós placuit fierí, et quadriennium in urbe ita flúxit ut potestátés ibi majórés nón essent.
When I first read this passage, I got stuck, because I kept thinking, majórés quam quid? Now I'm thinking it's just a general reference to high-ranking government officials, or to the top political positions. Is that right? For four years there was essentially anarchy, with nobody filling the offices of heads of state?
If I'm wrong, how ought I to understand potestátés majórés?
