Small powers

The international system is for the most part made up by small powers or small states. While a small power in the international system may never equal or surpass the effect of larger powers, they can nevertheless influence the workings of the international system together with others. The formalization of the division between small and great powers came about with the signing of the Treaty of Chaumont in 1814. Before that the assumption had been that all independent states were in theory equal regardless of actual strength and responsibilities. From the second half of the twentieth century, the bipolar power blocs decreased the strategic room for manoeuvre for smaller actors.

According to a 2017 review study, "What scholars can agree on is that small states generally prefer multilateralism as both a path to influence and a means to restrain larger states. Studies of influential small states indicate that they are able to develop issue-specific power to make up for what they lack in aggregate structural power. Small states can therefore develop power disproportionate relative to their size on the few issues of utmost importance to them. In addition to prioritization, small states have successfully employed the strategies of coalition-building and image-building. Even though small state administrations lack the resources of their larger counterparts, their informality, flexibility, and the autonomy of their diplomats can prove advantageous in negotiations and within institutional settings."

Almost all studies of power in international relations focus on great power politics and it will for this reason not be discussed here. For, as László Réczei noted, power status hinges on the capacity for violence: "If the notion of war were unknown in international relations, the definition of ‘small power’ would have no significance; just as in the domestic life of a nation it has no significance whether a man is less tall or has a weaker physique than his fellow citizen.

Most of the small-state studies that make up the backbone of the small power research tradition were carried out in the heyday of non-alignment by scholars such as David Vital, Robert Rothstein, Maurice East and Robert Keohane.

The weakening of the non-alignment movement during the 1970s coincided with a gradual decline in small-state studies, culminating in Peter Baehr’s critical appraisal of the research tradition in which he questioned smallness as a useful framework for analysis. The small-power category was first taken into serious account with David Mitrany’s study on world government (pax oecumenica) in 1933. Mitrany argued that the international community consisted only of two tiers of state powers: great and small.
