In this talk I show recent results on how many excited baryon resonances appear as systems of one meson and one baryon, or two mesons and one baryon, with the mesons being either pseudoscalar or vectors. Connection with experiment is made including a discussion on old predictions and recent results for the photoproduction of the Lambda(1405) resonance, as well as the prediction of one 1/2(+) baryon state around 1920 MeV which might have been seen in the gamma p -> K+Lambda reaction.
