Frans Baert's doctrine Baert was the founder of a methodology, known in Dutch as Baertdoctrine; regarding Flemish independence.Harry Van Velthoven, Karen Celis, Jasmien van Daele (2011) Waarheen met België?: van taalstrijd tot communautaire conflicten. p. 356 This doctrine, taken by some Flemish politicians, is a step-by-step strategy in order to get an independent Flemish State through democratic reforms of Belgium.

Each reform must follow three basic rules in order to reach a Flemish independence at the end: Each reform must be a significant step towards greater autonomy. Each reform should not prevent further reforms. Inside each reform, the price paid to the other negotiator should not be unreasonable.
