This thesis presents the results of recent investigations in the field of manganites using unbiased Monte Carlo techniques. It was found that the famous colossal magnetoresistance effect in the one-orbital model stems from the competition between charge-ordered insulating and ferromagnetic metallic states, which was also observed experimentally. The multiferroicity found in the E-phase of orthorombic manganites is also discussed, as well as the novel Truncated Polynomial Expansion Monte Carlo algorithm which will allow for simulations of larger systems in the future.
