Using small-instanton transitions to branes, we may generalize Higgs mechanism. This enables us to connect differently-regarded vacua. After introducing Higgs mechanism and small-instanton transitions, we show concrete examples of transition between string vacua in various string theories. The global consistency conditions of string theory guarantees anomaly freedom, which evades us from swampland.
