This thesis investigates semialgebraically connected semialgebraic groups over a sufficiently saturated real closed field R = R = (R, <, +, 0, ., 1) and is therefore contribution to the study of definable groups o o-minimal structures.

In this thesis we prove the following restricted version of Zilber's Trichotomy:
Let $K=(K,+,\cdot,v,\Gamma)$ be an algebraically closed valued field and let $(G,\+)$ be a K$-definable group that is either the multiplicative group or contains a finite index subgroup that is $ K$-definably isomorphic to a $K$-definable subgroup of $(K,+)$. Then if $\mathcal G=(G,\+,\ldots)$ is a strongly minimal non locally modular structure definable in $ K$ and expanding $(G,\oplus)$, it interprets an infinite field.
