Why the difference? If we look at education, the human capital argument might be an answer. But I theorize it might be due to different imperial institutions.

Historical work points towards the French being more diplomatic in their relations, and the Spanish more coercive(4/6)

Using census and historical mission data, I look at whether the French and Spanish had different impacts on long-term income for Indigenous in America (2/6)

For hegemonic peace, we focused on 3 hegemonic powers: the Delian League, the Peloponnesian League, and Rome.

Observation 5: The rise of Macedon, but neither the rise of Rome nor consolidating Greek Belligerents into leagues, is associated with peace (8/9)

Not only were democratic poleis not less violent, but the highest level of fighting was amongst democratic-democratic dyads. In our appendix we conducted robustness tests and our results held with different specifications. (7/9)

We were curious to see if a democratic peace held with the Greeks. It did not.

Observation 4: democratic dyads are associated with more traditional battles amongst Greek Belligerents. (6/9)

We then created dyads for the Greeks. In addition to regime, we were also interested in characteristics like size and distance.

Observation 3: less asymmetries in distance and more asymmetries in size are positively associated with dyadic battles amongst Greek Belligerents. (5/9)

We did monadic analysis of belligerents (280 unique ones). We then used a subset of the data with Greek poleis from 600-300 BCE.

Observation 2: battles are extremely skewed over belligerents and, of the Greek Belligerents, democratic ones are more associated with traditional battles (4/9)

When we plotted battles over time, we made our first observation.

Observation 1: battles are not a rare event in the Ancient world and are broadly declining from 400 to 40 BCE. (3/9)

To start our analysis we created a new ancient battles dataset using Jaques (2007), Montagu (2000), Taylor (2016; 2017), and Ray (2008; 2011; 2020) as sources. We used the records and Pleiades dataset to then map these battles to geographic coordinates. (2 /9)

Good day to digitize some maps

If anyone is at #winir2024, I’ll be on a panel there! I’m going to try and go to as many sessions as I can so feel free to let me know any of yours

Hello! I'm Patrick Fitzsimmons from George Mason. I do political economy and econ history. I am interested in the relationship between conflict, geography, institutions, and state-building. My #EconJMP and other papers can be found on my website:

Non-elites can revolt within their polity or there can be invasions from previous fringe societies. This leads to large states being fragmented into smaller states. I used a TWFE model and found that there was over a 100% increase in states after iron was introduced! (6/10)

The introduction of iron reduced elite power relative to non-elites. This is why we can observe political fragmentation in the early Iron Age. (5/10)

Bronze requires copper and tin, with the latter being relatively scarce. The relative scarcity of bronze components means that the elites have the most access to weapons due to cost. Weapons are needed for violent conquest and defense, so non-elites have to fall in line. (3/10)

Scholars have observed that the introduction of iron metallurgy was followed by political fragmentation in the Mediterranean (Ober, Manning, Scheidel, Boix, etc). I build on the theory that this is due to the increased violence potential non-elites experience. (2/10)

Looking forward to being part of this SEA session! #SEA2023
