This chapter provides the historical and scholarly context to the book’s main argument, and hence treats the military and economic developments that engulfed the Greek world in the late Classical and early Hellenistic periods. arguing that these should be seen as intrinsically connected. Following discussion of scholarly approaches to the economic transformation of the Greek world at this time, paying special attention to the old formalist–substantivist debate, the chapter advocates a closer look at the types of markets available, especially the market for labour. This market, the book contends, first appeared in a full form in the military sphere; accordingly, the chapter questions scholarly approaches and attitudes towards paid military service, debating especially the notion of ‘mercenary’ soldiers, who should better be conceived of as military wage labourers.

To ascertain soldiers’ potential status as wage labourers, this chapter discusses the process of initial enlistment and the ensuing terms of service, questioning especially whether soldiers enlisted of their own accord and retained their free status. It emerges that, from the reforms by Philip II of Macedonia onwards, political circumstances dictated a strong drift towards greater and at times complete reliance on so-called voluntary troops, who enlisted in exchange for pay. Thus, while the bulk of troops under Philip and Alexander were conscripts, these armies from the outset encouraged the enlistment of hired, voluntary troops in both elite and ordinary divisions. The lines between different troop types were blurred significantly under Alexander, whose conscript forces re-enlisted as hired men mid-way through his campaign. The Successors, whose often fickle claims to territory complicated the conscription of troops, were almost wholly reliant on voluntary troops. Accordingly, it is at this point that the epigraphic record attests military contracts, in which soldiers’ continued freedom of movement is guaranteed, alongside other terms of service. In the subsequent Hellenistic kingdoms, we see a return to conscription, especially in times of greatest need, alongside an enduring preference for professional, hired soldiers to man the standing armies.
