String interactions as a source of collective behaviour

The discovery of collective effects in small collision systems, have spurred a renewed interest in hadronization models, also as a source for collective effects all the way to large collision systems, where they are usually ascribed to the creation of a Quark--Gluon Plasma. In this topical mini-review, the microscopic model for string interactions, based on the Lund string hadronization model, developed with exactly this aim is reviewed, and some prospects for the future presented.
