Every national leader, scored across up to eight dimensions of tenure contribution — from governance and economy to politics and crisis response. Compare current form against the legacy they'll leave behind.
SourceTenure record + derivedMethodWeighted averageConfMedium✓ ReconstructableⓘLegacy Rating is the completed-tenure rating derived from sourced leadership dimensions and the recorded conditions of that tenure — on the published scale a score near 60 means the country broadly matched the benchmark trajectory over the mandate. Anything unsourced shows as no data. Full weights on the Methodology page.

Briefing
The story
Mladenov served as Prime Minister of Bulgaria. Mladenov has no composite Leadership score yet — too few dimensions have sourced data to compute one. Their standout dimension is Institutional Integrity (74/100).
The data & sources
Mladenov carries no composite rating: too few dimensions have sourced data, so it renders as "No data" rather than a filled-in guess. Diplomatic Conduct — no country-level data; shown as "No data" rather than inferred.
The risk read
Mladenov's governing-stability conditions have no sourced score yet, so treat leadership-driven country risk as unquantified here. For the full opportunity, market-pulse and resilience read, see Bulgaria's nation page.
The strategic read
A strategic read of Mladenov's governing profile. The sharpest institutional vulnerability is Politics (49/100).

Leadership Archetype
No distinct archetype
Uneven profile — 25-point spread from Institutional Integrity to Politics. No archetype rule matches that shape. This is a reading of the sourced stats — not a data gap.
SourceDerivedMethodRule-based classificationConfDeterministic✓ ReconstructableⓘArchetypes are derived automatically from the leadership stat profile — not hand-assigned. "No distinct archetype" means no classification rule matched; profile shape is assessed separately from the best-to-worst spread. A leader lacking enough sourced stats reads as "No data". A secondary archetype is added only when a stat scores exceptionally high.

Source: World Bank + derived·Method: Contribution·✓ ReconstructableⓘEach dimension measures change under the leader relative to global trends — how the indicator moved over their tenure, net of the world's move over the same window — not the country's absolute level. A score near 60 means performance broadly matched the benchmark trajectory; above = improved the country's standing, below = declined. Governance / Economy / Politics / Institutional Integrity from World Bank WGI, WDI and V-Dem trajectories; Vision from the country's innovation rank (WIPO patents + UNESCO tertiary), former leaders only (patents lag ~3 years); Crisis Response (World Bank + UCDP + WGI, an absolute response-quality scale) and Communication (GDELT) from tenure signals; Diplomacy (Diplomatic Conduct) is active-only. A tenure under six months, or an indicator whose series hasn't reached the term, shows as no data. Full model on the Methodology page.
