| You would first have to imagine portuguese being the lingua franca of the iberian peninsula. Hard to imagine. Passing that hurdle, then you'd have to imagine portuguese being the lingua franca of western europe. Hard to imagine that. Then of europe as a whole and so on. Almost a joke now. Portuguese was never the major power of it's immediate vicinity, let alone the world. Portugual, like the netherlands, was a glorified trading network rather than a legitimate empire. And portugual, like the netherlands, were minor powers within europe. Neither were major global powers as we understand the term and neither were powerful nor significant enough to produce a lingua franca of anything. |
The Portuguese managed to maintain territorial integrity and make their religion and language dominate it entirely, in what's today the 5th largest nation state by area. They also had to defend the longest coastline.
The Portuguese Empire did exist but AFAIK never did aspire to world hegemony like the U.K. Their idea of empire was best represented by something they briefly had which was the combined union with Brazil after its promotion from colony in 1815.
So, not an empire like the U.K. and never wanting to be an empire like the U.K. but also not a total failure to achieve some version of it, however short lived that was.
